Phys. Rev. Lett. 40, 416–419 (1978)Scaling Theory of the Asymmetric Anderson ModelSee Also: Erratum Received 9 September 1977; revised 30 November 1977; published in the issue dated 6 February 1978 A scaling theory is used to show that for temperatures T≪U, the properties of the asymmetric Anderson model (U≫|Ed|, Δ) are universal functions of the scaling invariants Δ and Ed*=Ed+(Δ/π)ln(W0/Δ), where W0 is the conduction electron bandwidth or U, whichever is smaller. Crossovers between various regimes of simple behavior as the temperature changes are described. |Ed*|≲Δ is identified as the criterion for a "mixed-valence" ground state, where the susceptibility ≈Δ-1. For -Ed*≫Δ, there is a local-moment regime with a Kondo temperature TK≈Δexp(πEd*/2Δ). © 1978 The American Physical Society URL:
